Abstract

Reactions of a boryl-substituted acyclic silylene with carbon dioxide and monoxide are reported. The former proceeds through oxygen atom abstraction, generating CO (with rearrangement of the putative silanone product through silyl-group transfer). The latter is characterized by reductive coupling of CO to give an ethynediolate fragment, which undergoes formal insertion into the Si−B bond. The net conversion of carbon dioxide with two equivalents of silylene offers a route for the three-electron reduction of CO ₂ to [C ₂ O ₂ ] ²⁻ .
